Toshiba Satellite E45-B4200 Troubleshooting

The device gets very warm and even hot, especially around the battery area.

The reason for the laptop overheating is insufficient cooling. Common causes for this are dust blocking the intake grills, exhaust ports, or a clogged-up fan.

To resolve this, shut down the laptop and open the bottom by removing any screws and the panel on the bottom.

Next, locate the fan and remove any dust that may be found on or in it. Ways to do this are to use a Q-tip to remove any material, air spray to blow the material out, or a vacuum to suck the material out.

Repeat this process for any intake grills or exhaust ports located around the laptop's exterior before reattaching the bottom panel and screws and powering it on again.

If cleaning the fan, intake grills, and exhaust ports doesn't resolve the issue then the fan is likely not working properly. This could be from the fan being unplugged so ensure everything is properly connected. If everything is connected then the issue is likely a broken fan.

In order to resolve this issue you must replace the fan with a new fan. You can find a replacement guide for this component with the link provided here. This replacement guide is with a slightly different version of the laptop but the only difference between the two is in the CPU so the fan replacement is the exact same process.

The device does not seem to be powering on.

The issue with the device not turning on could be that it is simply not charged. Even if it is plugged in this could be the issue still if the charger happens to be not properly working or is not properly plugged in.

Your laptop seems unresponsive and won’t reactivate after holding the power button. Try to remove the battery – if you need a guide, you can go here. Make sure your charger is also removed before continuing.

Hold the power button for at least 30 seconds to reset your CMOS/BIOS.

Return your charger and battery. Turn on device with button.

If the problem is not with the battery or charger then it could be with the display itself.

One way to check this is when you hit the power button to turn the device on, you can hear the PC making noise like it is starting such as the fan running but there is nothing on the screen.

Also, make sure the brightness is not turned all the way down as that could make the screen seem off when it's not off.

Another common issue for the device not powering on is a faulty battery or if the battery was knocked loose and just needs to be reinserted into the device. Ensure that the charger is plugged into the device and a wall and that the battery is still connected and in the device. If you've checked the battery may need to be replaced.

The device is not powering off by normal means.

If the device is not powering down then there are a few different ways to try and resolve this. These include force shutting down the device, using the command prompt to turn it off, disabling fast start-up, and then running Windows troubleshooter.

To force shut down the device, hold the power button down for 10-15 seconds before releasing it.

Disconnect all sources of power to the laptop including chargers and battery.

Wait 5-10 minutes before reconnecting the battery and chargers and powering the device on again.

The power settings could be incorrect and need troubleshooting.

Go to your search bar and type "Troubleshooting" and click it.

Click System and Security. Click Power. Run the troubleshooter.

That should detect your incorrect power settings.

Your driver could be out of date and not able to enter sleep mode, or it could be the reason your computer is unable to enter sleep mode.

The easiest way to fix this is to run a Windows update to get the latest drivers.

Windows may have hardware issues with the device, so check the Device Manager to check if any have been reported.

Press Windows key and 'X', and select Device manager. Locate the Bluetooth adapter and check if there is a yellow exclamation mark or a red X over it. Right click on device and click properties. In your General Tab you can find your device status.

The mousepad does not respond to touches, swipes, or clicks.

Your Toshiba laptop’s mousepad (or touchpad) is not working. It could be that your mousepad has been accidentally disabled.

If the touch pad does not seem to be disabled, try rebooting your computer.

Following these steps, hold the power button until the computer fully shuts down.

Remove the charger (if charging). Next, remove the battery. If you are having trouble, you can go here.

Wait for a few seconds, at least 10.

Reinsert the battery and charger. Turn on the laptop by pressing the button.

If you are still experiencing issues, it could be that your touchpad driver is out of date, and might need to be updated or reinstalled.

The buttons on the keyboard are sticky and occasionally get stuck.

The laptop keyboard is having a heard time typing since the keys seem to be sticky. The keyboard needs to be cleaned.

First, get a bottle of cleaning rubbing alcohol. Make sure your computer is off before cleaning. This would be best to keep everything safer so that nothing is running while you perform maintenance.

Remove any large debris. Make sure that the laptop is open and try to face the keyboard upside down for better cleaning. Use a gentle cloth, preferably a microfiber towel, and clean out larger debris from the cracks between the keys.

After this step, take damp (not dripping) cotton swabs with cleaning rubbing alcohol and gently wipe away between and around the keys.

If your keys remain sticky, try removing them and cleaning them down that way. After, replace back into intended location.

If there are still issues with the keyboard after cleaning, there is a possibility that the keys themselves are broken.

You can gently pry off the keys with a small, flat object like a flathead.

Take your flathead and gently pry the plastic out from under the metal bracket. flip it over and gently push into place. It should snap into place after light pressure.

Take the key cap and snap into place.
